Regulator swapping.

Hey, I currently own a 800psi output 48/4500 empire tank. The gun im getting requires 550psi, so I am going to get an adjustable ninja reg. im concerned about taking off the reg and installin the new one, Should I hand screw the new one in? Can I use teflon tape or blue loctite on the threads before I screw it in? Is it safe to switch those regs? Thanks.

also another question, Is it safe to remove all shims from the standard ninja reg? and what pressure output will it give?

To be honest, for questions like that, it's probably best to call up a professional over at Ninja.If anything went wrong, I doubt your tank's warranty and your medical insurance would accept a plea of "This random guy on the internet said it would be ok".

I believe that taking out all the shims wil set it to low pressure,but as for the reg swap,it's probably best to call up ninja.Just make sure your tank is fully emptied before you take off the bonnet,or it will shoot off like a bullet.

Sometimes those regs are a pain to get off. When I swapped mine I had to clamp the fill nipple in a vice and use a band wrench because some companies use aggressive locitite. Also be very clean and have a clean work environment, you don't want anything getting into that tank when the regs off and don't use any rags etc. to clean the threads out, just install.

Shooting it dry in my experience. You get some good practice in too. Another thing you can do is take your on off asa off your gun ( if you can), screw in your tank and then screw in the on off knob part way. You don't even need macro line and it can be very fast and loud or very slow and quiet, depending on how much u screw your asa in.

Screw out your old one and screw in your new one, simple as that, just drain the air from the tank first.
Played with a regulator that's just screwed in since 2008. I'd advice against using locktite, as if you need to take it of, it's a complete bitch to do and you might ruin your tank or regulator.

I would add some thread sealer/threadlocker .. loctite makes a low threadlocker/ good thread sealer .. #5451, it's purple. Easy to remove, but the idea here is you have a pressurized vessel, with metal to metal threads. That is never a good thing. Air leakage is easy to occur, so a thread sealer is a good idea.

Ok, still looking to see if removing all the shims from a ninja reg would be ok.

I believe that taking out all the shims wil set it to low pressure

Yes but I do not recommend it.Removing all the shims would get you to 450 to 550 psi.

You have a high pressure tank, your gun operates at 550PSI, or so you say. Why would you want to lower the pressure in your tank ? The way it is set up now, you will always be able to operate your marker until the tank gets so low that it cannot fire the solenoid anymore. Why take the chance on misfires by trying to run at threshhold pressure ? That really doesn't make sense to me.

you shuld try it. take the shims out and see about how many shots you get between fills, and if you have any misfires or ball breaks, and then put them back in and do the same thing. then come back and let us know which was better if there was any difference at all. the only other issue would be that if you take the shims out, it's highly likely that over time, you will forget where the heck you put them, then if you want to sell the tank, you're stuck having to buy new shims.
